The Brazil international played in the role in the FA Cup defeat at Wolverhampton Wanderers on Monday.

Dejan Lovren became the latest Liverpool centre-back to pick up an injury when he came off after five minutes of the third-round tie, clutching his left hamstring.

Joe Gomez remains still sidelined with a lower leg fracture, but Matip took part in team training on Thursday for the first time since fracturing his collarbone against Paris Saint-Germain last month.

"Joel trained yesterday first time with the team, which is really good, but we have to see," Klopp told a news conference on Friday. "We have to decide day-by-day how he is doing. He feels good, and that's good for us.

"Hendo [Jordan Henderson] will train today, first time, and we will see what that means exactly. Adam [Lallana] is out. Dejan out. Joe, of course, out. All are improving, [but] I know they are not available.

"I don't know [when Lovren is back]. It's not that serious. It's a muscle thing and I would expect him back maybe after Crystal Palace -- I'm not sure. We have to see."

Virgil van Dijk sat out the game at Wolves but is set to return for Saturday's trip to Brighton.

Depending on Matip's fitness, Fabinho, normally a defensive midfielder, could play at centre-back as the Premier League leaders look to respond to back-to-back defeats.

"If Fabinho has to play as a centre-half, we are not sure, he has played it before, but of course we do that on the training pitch," Klopp said.

"You have helpful players around, one player usually can't decide a game -- up front it happens from time to time -- but in defence you need the boys around you. We speak in the week, but try to not make it more complicated than it is."
